ELARD LUDDE, OF MASPETH, NElV YORK.

POWDER-BLOWER.

SPECIFICATION forming part of Letters Patent No. 459,915, dated September 22, 1891.

Application filed December 23, 1890. Serial No 375,593. (No model.)

T0 00% whom it may concern.-

Be it known that I, ELARD LUDDE, a citizen of the United States, residing at Maspeth, in the county of Queens and State of New York, have invented certain new and useful Improvements in Powder-Blowers, of which the following is a specification.

This invention relates to a combined powder blower and receptacle for insect or other powder, from which the powder can be discharged in moderate sprays or clouds by the action of the blower, it being ready for use in the receptacle 011 cutting off a small por tion at the point of the receptacle; and the invention consists of a combined powder blower and receptacle, which comprises anexterior conical shell provided with a ringshaped bottom, a hemispherical elastic bulb secured by the circumferential flange to said bottom and an interior tube that extends from the apex of the conical receptacle to near the bottom, of the same, so as to force the powder in sprays or clouds to the outside of the same by the action of the bulb, as will be fully described hereinafter, and finally pointed out in the claim.

In the accompanying drawings, Figure 1 represents a side elevation of my improved powder-blower. Fig. 2 is a vertical central section of the same; and Fig. 3 isa horizontal section on the line 3 3, Fig. 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a conical shell, which is preferably made of pasteboard or other stout material, and B the ring-shaped bottom of the same, which is formed of two superposed rings 1) b, that are provided at their inner meeting edges with recesses Z), forming a seat for the circumferential flange cl of a hemispherical bulb D. The two rings 1) b are united to each other and to the flange d of the bulb by gluing them carefully together, so that the bulb is firmly retained by the same. A dischargetube 0 extends from the apex of the conical receptacle A in downward direction to near the bottom of the same, said tube communicating with an opening at the apex of the re ceptacle A when the powder-blower is to be used. Before using the powder-blower the opening at the apex is closed by an exterior layer of paper that covers the receptacle A, as shown in Fig. 1.

moved, so that a small opening at the point of the shell is formed for the escape of the powder. Before cementing the bottom B into the conical shell A the latter is filled with insect or other powder, and the bottom, with its bulb D,then placed in position at the lower end of the shell. Then the blower is to be used, the bulb is pressed inwardly, as shown in dotted lines in Fig. 2, whereby a cloud of powder will be ejected, the bulb returning into its normal position when the pressure is released and being then ready for the next ejection of the powder. The powder-blower is readily operated by holding it between the fingers and operating the bulb with the thumb, so that the powder is forced out in the formof a finely-divided spray or cloud, by which the uniform distribution of the powder and effective action of the same are produced.

As the powder receptacle and blower are combined and the powder is stored away in the receptacle, the device is complete in itself and can be used at any time with great efficiency until all, the powder is ejected from the shell. It can be manufactured cheaply of the powder is lost in operating it and as the same is ready for immediate use without requiring the special filling of the receptacle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A combined powder blower and package composed of a conical receptacle having an opening at its point or apex, a fixed interior supply-tube extending from the apex to a point near the bottom, a ring-shaped bottom formed of two layers provided at their inner meeting edges with a seat, and an elastic bulb having an outwardly-bent circumferential flange attached to the seat of the double bottom, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

ELARD LUDDE.
